IMPROVED BURNISHING-MACHINE.

Specification forming part of Letters Patent NO. 52,336. (lated January30, 1866.

To all whom it may concern:

Be it known that I, NATHAN O. STOW, of Stoneham, in the county ofMiddlesex and State of Massachusetts, have Invented a Machine forBurnishing the Edges of Shoe-Soles, which I call a Shoe-Edge-Burnishing`Machine; 77 and I do hereby declare that the following,I is a full andexact description thereof, reference bein g had to the accompanyingdrawings, and to the letters of reference marked thereon.

The nature of my invention consists in constructing a machine composedof a conical wheel whose surface is composed of fillets and beadsalternately, as shown at F in all' the i figures, each fillet and itsadjoining bead makinp,` a complete iron 77 for burnishing' and ashoe-holder in which the shoe to be operated upon is fastened. Thewhole, when operated, will burnish the edge of a shoe-sole as well as itcould befdone by hand and much more rapidly.

To enable others skilled in the art to make w and use my invention, Iwill proceed to describe its construction and use.

In the drawings, Figure l is a perspective View of the machine. Fig. 2is a plan of the machine. :Figz 3 is'a- Vertical section of the machine.

A in all the fignres represents the base or iioor upon which the machinestands. B in all the fig'ures represents the body or frame of themachine. G and G' are standards, the upper ends of which form bearingsin which the shaft U of the burnishing-wheelruns. Upon the shaftU isaffixed at one end the balance-wheel H, at the other end theburnishing'-wheel I`, and at about the middle the driving-pulley P.

The burnishing-wheel F in all the fig'ures is made of any suitablemetal. Its exact shape is shown in section at F in Fig. 3. Its outersurface is eomposed of fillets f f' f f', &c., and of beads b b' b b',&c., alternately, as shown at F, F1' g. 3. Afillet and head combinedmake an iron. Thus I call that part of the burnishing-wheel that liesbetween the dotted lines 8 t and a v, Fig. 3, an iron. The irons are ofdifferent dimensions to suit the different kinds of shoes. The edge of athick shoesole would be burnished .on the iron whose fillet and bead arerepresented by f and b,Fig. 3, while the edge of a thin shoe-sole wouldbe burnished on the iron whose fillet and bead are represented by f` andb, Fig'. 3.

To the standard G is attached a lamp, N, which serves when burning tokeep the burnishing-wheel F at the proper temperature. i

The shoe S to be operated upon is held in position by a device which Icall a holder;7 and which consists of a standard, O, provided with afoot, R, Fig. 3, movable in a socket in the lever I, and also movable inthe direction of its length in the standard-piece O,in which it-is held.in any desired position by the setscrew T. The lever I is operated bythe foot to raise or lower the holder. M forms a fulcrum for the leverI.

Attached to the standard O is a fixed arm, X, Figs. l and 3, and amovable arm or lever, E. The fixed arm X, together with the link andblock O, form an arrangement for holding in any desired position thelever E. The lever E pivots upon the pin Z, Fig. 3.

To the lever E, by means of the link n, is attached a sliding rest, Dand D', Figs. l and 2, and D' and K in Fig. 8. This sliding rest moveswith the lever E and assists to hold the shoe S. The end ot' the lever Eis rounded off, as shown by V, Fig. 3, in such a manner as to admit ofits ent-rance into the holes usually made in shoe-lasts. The shoe beingoperated upon is indicated by S, and the last by L.

The operation of the machine is this: The lamp N is lighted and theburnishing-Wheel set in motion. A shoe before it is taken from the lastis placed upon the end V of the lever E and adjusted to the properinclination by raising' or lowering the lever E by means of the link andblock O. When this adjustment is complete the operator takes a firmgrasp, one hand upon the lever E and fixed arm X and the other hand uponthe shoe, and, placing it in proper position under the burnishin g-Wheel F, he puts his foot upon the lever I and thus brings the shoe upunder and against that part of the burnishing-wheel which fits the shoeunder operation. As the edge in immediate contact is finished the shoeis moved along and guided by the operator nut-il the entire edge haspassed under the burnishingwheel.

What I elaim as my ivention, and desire to secure by Letters Patent,is-- l. A rotatingburnishng-wheel formed substantally as desoribed, andfor the purpose set forth.

2. The shoe-holder made substantially as descrbed, and for the purposeset forth.
